Keeping up your credit card bills can be quite challenging especially if you have limited funds. I just paid my credit card earlier and I have to withdraw from my savings since I did not receive the money I am expecting this week. If you are a credit card user it is your responsibility to keep up the deadlines so that it will not incur charges. If you pay your bills in full every deadline date, there will be no extra charges at all. If you only pay for a minimum charges, it is like you are paying for an extra amount for your purchases.
Before you buy or make an expense think twice if you can pay within your means. If you cannot, it will be a problem later keeping up the bills. It may accumulate later and can lead to debt.
